IMPRovEMEN-r IN STEAM-TRAPS.

Specification forming part of Letters Patent No. 143;761, dated October 21,1873; application filed February 21, 1873.

` slide-valve operated by a iioat, and so balanced that it operates lwith equal freedom under any pressure. This slide-valve and iioat are applied in a metallic case that has screw-plugs or valves for regulating the speed of the discharge water of condensation, and for blowing out obstructions.`

In the drawing, Figure l is a vertical section of the said trap, and Fig. 2 is a partial section of a modification of said apparatus.

The vessel a is connected with the inlet-pipev b, through which the Water of condensation flows, and the escape-pipe d delivers the water from the case.V Within the vessel a are the partitions e and f, dividing the space into the chambers g', 7L, and 7c. The float l is in the chamber g, that receives the water of condensation from the pipe b, and a deflector, a, checks the force ofthe water and prevents it striking the float. The tubular valve t' surrounds the tubular seat o. In the tube o are discharge openings 2, and in the tube t' are openings 3, that admit steam' or water between the closed end of the tube o and the float Z, so as to equalizepressure and allow the loat to rise and fall freely by the change of Water-level in the chamber g. As the water runs into this chamber g, the iioat l rises, and its tubular valve 'i uncovers the holes 2 in o, and allows the water to be `ej ected by the pressure into the chamber 7L, and escape by the opening 4 in the partition f, and ilow away by the pipe d. As the waterlevel in g descends, and vdth it the iioat I, the

openings 2 are covered and the further iioiv of water stopped` until the float rises again. The oat l is guided at 5 in the cap 1, and at the top is the cover s and escape-air cock t,

which latter may be employed, if desired. The screw-plug o, applied to the hole 4 in the partition c, and operated by the hand-wheel o, serves to arrest the operation of the apparatus when desired, or regulate the escape of the water of condensation. The screw-plug w and blow-oft' cock w serve to empty the trap or blow off sediment when required.

In Fig. 2 corresponding parts areshown, and the operations are the same, except that the float is made as an open vessel and the delivery of the water of condensation takes place through it. In the position shown, the Water is blowing ofi through the openings 2 in thc tubular seat o, and, as soon as sufficient Weight of water has passed out of the oat t0 allow it to rise, the tube@- acts as a valve to close the openings 2, until a further rise in the Water causes it to ilow over the edge of the iioat and sink the same, and the operations.

are repeated.

I claim as my invention- 1. The openings 3 in the tube fi above thc tubular seat o, in combination with the tubular seat o, openings h, iloat Z, and chamber g, substantially as set forth.

2. The arrangement of the partitions e f in the vessel a, to form the Vchambers g h k, in combination with the stop-plugs c w, and blow` off cock 00, float Z, and tubular valve fi, substantially as set forth.
